Common name: grand pleurobranch

General information

The Atlantic Side-Gill Slug, scientifically known as Pleurobranchus grandis, is a species of sea slug belonging to the order Nudibranchia. Despite being called a 'slug', it is not a true nudibranch but rather a member of the Pleurobranchidae family. These creatures are known for their large size and distinctive side gills, which are used for respiration.

Care

Caring for Pleurobranchus grandis in a home aquarium requires a specialized setup that mimics their natural environment. They are not common in the aquarium trade and are recommended for advanced hobbyists. A tank with a sandy substrate and plenty of live rock for hiding is essential. They feed on a diet of sponges and other sessile invertebrates, so it's crucial to ensure a sustainable food source.

Reproduction

Reproduction in Pleurobranchus grandis involves laying egg masses on hard substrates. In captivity, breeding is rare, but if conditions are right, they may spawn. The larvae are planktonic before settling and metamorphosing into their adult form.

Habitat

Pleurobranchus grandis is found in the Western Atlantic Ocean, from North Carolina to Brazil, including the Gulf of Mexico and the Caribbean Sea. They inhabit sandy and rocky substrates, often hiding during the day and becoming more active at night.
